Why does MEX Compiler work in earlier versions of MATLAB but not in recent versions?

I am trying to compile a 'C' mex function. This worked in earlier versions of matlab but with MATLAB R2020a, and the MinGW compiler, I am getting the following warnings and errors:

Error using mex
Warning: corrupt .drectve at end of def file

How can I fix this?

To resolve this issue, please ensure all dependencies are compiled with the same compiler and version of MATLAB. When all dependencies are recompiled with the currently used version of Matlab and compiler, the application will be able to compile and run successfully.
